When I took over the running of the internal employee portal at this organization, the site was a hard-to-read tangle of columns, with no real sections, and a difficult-to-follow archive function. I created a new architecture with clear sections, and a simple archive.
The design I took over was hard to update and even harder to read. There were no sections, and columns ran for indeterminate lengths. Aside from checking recent financial performance, no one read it, and few people submitted information.
After several miserable months with the inadequate design, I proposed a new layout, and worked with a designer. It works more as a newsmagazine, with sections for different kind of information, from hot news to software updates. Archiving is easy, and readers can easily find older entries.
The result was much greater employee engagement, and a greater volume of submissions from various offices and departments.
Note: the squirrels-making-coffee photo at the top is mine as well, for a theme from the main office.
